My raspberry plants have yellow leaf fungus and I need to address it or lose the plants. They are planted with good air circulation and in direct sun, but we have had a very wet spring and they developed fungus just as the fruit was coming on. I sprayed them rather than lose them, but do I need to discard the berries or can I soak them to clean off the fungicide?
Bonide Liquid Copper Fungicide Concentrate can be applied to raspberries. It can be applied at the start of following and continue every 7-10 days ( not exceeding 186 fl oz per year) until harvest if used as directed on the product label.
